PROBLEM TO BE SOLVED: To improve maintainability of a thrust receiving mechanism while reducing a manufacturing cost of the thrust receiving mechanism. SOLUTION: Race plates 125 to 127 and cages 123 and 124 are fixed by columnar straight pin-shaped first and second pins 128 and 129 having no stepped part. Thus, a manufacturing cost of the first and second pins 128 and 129 can be reduced. Since a head part has no flange part, when disassembling and maintaining the thrust receiving mechanism, a problem such as the cages interfere with the flange part is caused little, and the maintainability of the thrust receiving mechanism 120 can be improved. Thus, while reducing the manufacturing cost of the thrust receiving mechanism 120, the maintainability of the thrust receiving mechanism 120 can be improved.
